To celebrate next week's PS3/PC release of the Apocalypse DLC Map Pack, @Treyarch is turning on Double XP this weekend for all platforms! Running from Friday, September 20 (10am/PDT) through Monday, September 23 (10am/PDT), earn twice the XP on all of your Multiplayer play.

Apocalypse marks Treyarch's fourth and final DLC map pack for Call of Duty: Black Ops 2, capping-off the year with two all-new Multiplayer Maps, two re-imagined fan- favorite Multiplayer classics, and an alternate-reality Dieselpunk Zombies experience that transports players to the undead-infested trenches of a World War I battlefield. Apocalypse is available now on Xbox LIVE and comes to PS3 and PC on September 26.
